가정에서 배출되는 오수는 고농도 오수(화장실, 주방 등에서 배출)와 저농도 오수(욕실, 세탁기 등에서 배출)로 구분할 수 있고, 이들은 일반적으로 각각 50% 정도의 비율로 배출된다.Sewage discharged from homes can be divided into high-concentration sewage (discharged from bathrooms, kitchens, etc.) and low-concentration sewage (discharged from bathrooms, washing machines, etc.), and these are generally discharged at a rate of about 50% each.
이들을 모두 하수관으로 배출하여 하수처리장에서 정화하도록 하는 경우, 하수처리장에 과부하가 발생하므로, 고농도 오수만을 하수관으로 배출하고, 저농도 오수는 아파트 단지 내에 설치된 정화장치에 의해 정화하여 중수로 활용하거나 하천에 유출하기 위한 연구가 이루어지고 있다.If all of this is discharged into the sewer pipe and purified at a sewage treatment plant, the sewage treatment plant will be overloaded, so only high-concentration sewage is discharged into the sewer pipe, and low-concentration sewage is purified by a purification device installed in the apartment complex and used as gray water or discharged into the river. Research is being conducted for this purpose.

이는 다음과 같은 효과가 있다.This has the following effects:
첫째, 여재의 압축에 의한 여과 효율의 증대, 여재의 이완 및 2중 세척에 의한 초기 여과성능의 안정적 회복이 가능하므로, 장치의 설치를 위한 부지를 최소화하면서도 우수한 정화 성능의 확보가 가능하다.First, since the filtration efficiency is increased by compression of the filter medium, the initial filtration performance can be stably restored by the relaxation of the filter medium, and double washing, it is possible to secure excellent purification performance while minimizing the site for installation of the device.
둘째, 정화 공정 및 세척(역세) 공정이 전자동에 의해 이루어지므로, 세척수의 배출, 약품의 추가주입, 여재의 교체 등을 제외하고는, 사용 및 유지관리를 위한 전문 운영 인력의 배치가 필요없고, 운영 비용이 거의 소요되지 않는다.Second, since the purification process and washing (backwashing) process are carried out fully automatically, there is no need to deploy professional operating personnel for use and maintenance, except for discharging washing water, additional injection of chemicals, and replacement of filter media. There are almost no operating costs.
셋째, 소독조에 의해 난분해성 오염물질, 유해 미생물의 제거를 수행할 수 있다.Third, non-decomposable contaminants and harmful microorganisms can be removed using a disinfection tank.
